To :alllwltom/ t .mag/Concern Be fit known thatL We, EDMUND R. ,Jeudis-.n i'Nsiir. and fXLnxANDER- E.v FREDERICK..bothvk citizens ot'theaUnited Statesyand residents A of- ,Merton, Vcounty of Vaukesha,4State of, a lVisconsin, and lo-f Milwaukeein the .county of Milwaukeeand State of Visc-onsin, re-V spectively, have -invented certain new anduseful Improvements vliin Plate-.Setting Tools l:- andV We do herebydeclare lthat the followingv is a full, clear, and "exact 'descriptionthereof. l l y This `invention.'relates tofplate setting tools.

Incertain kinds of masonryV Work it 1 be comes necessary to set.relatively fragile fiati plates in constricted 'placesandt-o evenlyposition the plate onLfresh cement or mortarA Without any-irregularitiesoccurring.I This Work, when done solely by manual means, `is n extremely4diflicult and is laborious and-slow,V

and in addition t0 this,rit isl almost impose sible :undervthesev`conditions to ,secure an 1 absolutely perfect positioning andxqoiningrof the plaztewto adj acentportions of .the struc.- ture. An-instancei-fofthis -Work isz found in certain types of filtrationf--lplan-ts-finf which thei fragileY ceramic 'pla-tes commonly known as;filtroslplates'- are employed; .ThesenV plates have tobe set Withirn a1very smallchannel ilikevspace and 'up on v a fresh 'layer yof softcement. In view of-fthei-rfragile nature, o

of the@limited space, and-of -thefzairtight setting .of therapla-tes`:upon the i cement, rvthis Work-fis lfound-to bef-very dificu-lt andfre-` quent breaking of the plates andwim-properf fitting occurs.

This invention is designed to ,overcome the above noted defects,andfobj'ectsmofsuch invention are to provide a plate setting tool whichis adapted to handle fragile plates and to sea-t such plates in therestricted place, and to accurately gauge the setting of the plate so asto secure an air tight ]oint and a uniform positioning of the plate Withreference to the fresh cement.

An embodiment of the invention is shown in the accompanying drawings, inWhich:-

Figure 1 is a longitudinal sectional View through the plate settingtool, such View corresponding to a section on the line 1-1 of Figure 2,and showing the tool in relation to the plate and channel Within whichsuch plate is set.

This finger is further: provided with an aperture v13;preferably havingr rounded j edges, as shown in Figurel, and 'apin-v14de passed through such aperture and pivotally attached to the linger11 by any suitable means as for example by means of the pivot pin 15.This pin has its inner end riveted or otherwise secured to a flexiblemetal strap of spring like material,V as indicated at 16 in Figures 1and 2, the other e-nd of such strap being secured to the end bar 4.-.The strap 16 is preferably positioned, as shown in Figure 2, directlybeneath the handle 6 so as to be readily gripped by the operator.

In using this device, fresh mortar or cement 17 is placed upon thecurved slanting shoulders 18 of the channel (see Figure 1). Thereafter,-a plate 10 is positioned between channel andv |`With respect ftoanadjacent,plateas ,the fin gerV 8 'is adapted `to, contactIWiththe next,

vtured, may be rapidly used and may the finger 7 and the finger 11 andagainst the finger 8. Thereafter, the operator grips the handle andslips his finger bene-ath the strap 16 and draws upwardly upon suchstrap. This rocks the clamping finger 11 inwardly and grips the platesecurely. The operator may then lift the frame and plate into positionwith reference to the channeled masonry, or support, as shown in Figure1, and may lower the device into position. During this operation, theoperator causes the finger 7 to Contact with one of the walls 9 of thesupport or channel and causes the` finger 8 to contact with, an adjacentpreviously laid plate. The frame and plate are lowered until theprojections or members 3 rest upon the upper surface 19 of the channelmasonry, as shown in Figure 1, and thus accurately position the platewith reference to such upper surface, and insure the correct positioningof the corner and edges of the -plate within the fresh cement 17.Thereafter, the operator loosens his grip upon the strap 16 whichdisconnects the frame from the plate, and then withdraws the frame.

It will be seen that this operation may be most readily performed andthat itv will result at all times in an accurately laid plate both withreference to the depth to which the plate is set and also to the exactlocation of the plate with reference to the adj acent channel masonry.

It will further be seen that this plate setting tool may be most cheaplymanufacbe employed by an unskilled laborer.

From actual competitive testsbetween the speed and accuracy of thesetting of the plates when this tool was used and the setting of the,plates in the usual manner, it has been found that the use of this toolboth improves the accuracy of setting and also vastly increases thespeed. It has been found that a single workman equipped with this toolcan lay as many plates as five or six ordinary workmen, and that thelaying of the plates with this tool is a great deal more accurate andcertain than with the methods heretofore employed.

ber,

Although the invention has been described in considerable detail, it isto be understood that the invention may be variously embodied and is,therefore, to be limited only as claimed.

We claim:

. 1. A plate setting tool comprising a frame having downwardly extendinglingers securely attached thereto at one end and having a movable fingerpivotally associated with said frame at the other end, said frame havinga transversely extending manipulating handle, and a flexible memberextending across said frame below said handle to said pivotally mountedfinger, whereby when said flexible member is manipulated, said finger ismoved into plate clamping position.

2. A plate setting tool comprising a frame having downwardly extendingfingers at its ends, one of said fin ers being movably associated withsaid rame, a flexible strap like member extending transversely of saidframe and having one end secured to said movable finger, a manipulatinghandle secured to said frame above said flexible memand gaugingprojections extending outwardly from said frame and adapted to regulatethe depth of setting of said plate.

3. A plate setting tool comprising a` frame having downwardly extendingfingers at its ends, one of said fingers being movably associated withsaid frame, a` flexible strap like member extending transversely of saidframe and having one end secured. to said movable finger, a manipulatinghandle secured to said frame above said flexible member, gaugingprojections extending outwardly from said frame and adapted to Vregulatethe depth of setting of said plate,

and a positioning .finger secured to the side of said frame, all of saidfingers having tapered lower portions.

In testimony that we claim the foregoing we have hereunto set our handslat Milwaukee, in the county of Milwaukee and Stat-e of Wisconsin.
